One of the richest sources of Lutein and Zeaxanthin in nature is Marigold flowers.
Production Process:
Parry Nutraceuticals takes extreme care in growing and selecting marigold flower varieties, under a captive contract farming network, covering 5000 acres and 3000 progressive farmers to produce high quality lutein esters. A team of experienced and dedicated agro professionals monitor the process and restricts use of pesticides and herbicides to internationally accepted guidelines. The harvested flowers are then dehydrated to prevent further degradation of active ingredients.
The Lutein esters are derived from marigold oleoresin by selective precipitation and subsequent purification steps by re-crystallization, removing all other unwanted inactive materials like Waxes, Lipids, Triglycerides and purified to the extent of more than 95% and obtained in the form of pure crystals free from all impurities and any solvent residues.
The pure crystals are then formulated to desired concentrations ranging from 5% to 40% as "Lutein Esters," Zeaxanthin 5% to 20% and Lutein with Zeaxanthin combinations, all in the form of powder, beadlets, and oil dispersions. All the ingredients used along with the active principles are food grade, vegetarian and are allowed by all pharmacopoeias as carriers. These bulk formulations can be easily converted into dosage forms like soft gels, capsules, and tablets.
